Conference audio quality realy poor

[Death80]

Hi,
i've done some test, the quality of a call between 2 internal extension is realy good, the quality of incoming call is realy good, but when i make a conference the audio quality is realy realy poor and don't matter who are partecipants.

Is there a way to increase audio quality in conference?

What do you mean by audio quality? Is there choopy sound? Do you have low sound? Do you have echo? Give as much details as you can...

Hi,
During the conference, u hear voices realy bad, voices are distorted, feel like an old vinyl ruined disk

u hear like "gr gr gr gr gr gr g r gr gr gr gr"

No echo

Hmmm...
That sounds like if you where using a VM using another kernel (not provided by Elastix) causing a synchronization issue with dahdi, or that you need more CPU resources.
What is the output for:
uname -a
rpm -qa | grep dahdi
cat /proc/couinfo
